H M. ANDERSON GAS DISCHARGING DEVICE FOR SAFES Filed Nov. 7, 1928Patented Dec. 30, 1930 UNITED STATES PATENT OFFICE H MILLER ANDERSON, OFCHICAGO, ILLINOIS, ASSIGNOR, BY MESNE ASSIGNMENTS, TO THE LAKE ERIECHEMICAL COMPANY, OF CLEVELAND, OHIO, A CORPORATION OF OHIO eGAS-DISCHARGING Application filed November into an enclosure such as avault or safe.

Numerous other objects and advantages of the invention will be apparentas it is better understood from the following description, which, takenin connection with the accompanying drawings, discloses a preferredembodiment thereof.

In the drawings:

Figure 1 is a perspective view of an improved gas discharging mechanismconstructed in accordance with the invention Fig. 2 is a frontelevational view of the same;

Fig. 3 is a vertical section, partly in elevation, showing the parts ofthe poison gas bomb firing mechanism; and

Fig. 4 is a top plan view, partly in section, of the supporting bracketfor the firing mechanism and the gas bomb.

One of the usual modes of application of the invention is to a vaultdoor, a fragment of which is shown at 11 in Fig. 3. The vault door 11 isprovided with the usual combination lock contained within the 60 x orcasing 12, mounted on the inner surface of the door and controlling theoperation of the usualbolt work, not shown, which is advanced intosuitable keepers in the door frame to lock the vault and retracted torelease the vault door for opening movement.

A common mode of procedure on the part of a burglar attempting to forcean entry into a vault is to punch or blow in, or otherwise dislocate thecombination box from the vault door. The illustrative gas dischargingmechanism is shown as controlled in its operation by such dislocation ofthe combination box.

The various parts of the gas bomb discharging mechanism are supported bya bracket 13 comprising a vertically arranged plate member 14 providedwith holes 15 whereby it may be secured to the inner surface of thevault door 11. The upper end of the bracket plate 14 is provided with aninwardly extending overhanging shelf or support 16, and the lownEvroEron. SAFES 7, 1928. Serial No. 317,811.

er end of said plate 14 with a pair of inwardly extending horizontalsupporting lugs 17.

Secured to the plate 14 and projecting inwardly therefrom are superposedsupporting rods 18 and 19. The upper supporting rod 18 is made somewhatshorter in length than the lower rod 19, as shown in Figs. 1 and 3.These supporting rods 18 and 19 are respectively provided with alinedvertical holes 20 and 21 constituting bearings for the passage of avertical firing pin 22. The upper end of the firing pin 22 extendsapproximately to the lower surface of the shelf 16 and said pin isformed with a channel or socket 23 extending part way down from its top.The channel or socket 23 receives a coil. spring 24, the upper end ofwhich engages the lower surface of the shelf 16 and the lower end thebottom 25 of the socket 23. When the firing pin is released, the spring24, which is maintained normally under compression, will cause thefiring pin to drop with a sharp blow and hit the cap or firing plungerof a poison gas bomb.

The firing pin 22 is released for operation by a trigger mechanism, asfollows:

As shown in Fig. 3, the pin 22 is provided with an annular horizontalgroove 26 located in that portion of the pin which is normally disposedwithin the bearing hole 20 in the upper supporting rod 18. A trigger pin27 projects through a hole in the free end of the rod 18, in registrywith the groove 26, and enters said groove normally to hold the firingpin in its elevated inoperative position. The 1 trigger pin 27 issecured at 28 in any suitable manner to the trigger operating bar 29.This bar 29 is provided with a yoke 30 at its lower end which embracesthe squared end portion 31 of the rod 19. From the opposite wings ofsaid yoke, ears 32 project parallel with the sides of said portion 31and are pivoted thereto in any suitable manner, as shown at 33. -Thisconstruction permits a pivotal swinging movement of the triggeroperating bar 29.

The trigger operating bar 29 is bent at 34 into the horizontal portion35, which overlies the shelf 16, and thence is rebent at 36 into theupstanding end 37.

This end 37 is made I )ng enough to extend upwardly beyond the ottom ofthe combination box 12 and is seured by any suitable means, such asascrew 8 to the rear face of the combination box. L leaf spring 39 bearsagainst the trigger perating bar 29 and exerts pressure thereon thrustsaid bar outwardly. This leaf pring 39 is secured at its opposite ends40 y screws 41 fast to the horizontal shelf 16. Vith the above describedconstruction, disocation of the combination box from any ause, willimpart a pivotal swinging movement, assisted by thespring 39, to thetrigger vperating bar 29, in a direction away from he end of the rod 18.Such movement about he axis 33 will withdraw the trigger pin27 From thegroove 26 in the firing pin 22 and )ermit the spring 24 to operate thefiring pin n the manner hereinbefore described. The eaf spring 39 ismade strong enough to in- :ure a quick, positive operating movement .0the bar 29 whenever the combination box s dislocated.

As shown in Fig. 3, the groove 26 in the iring pin 22 may be maderelatively shallow. Hence, very little movement is required to lisengagethe trigger pin 27 from the firing in 22, and the action is thereforeinstantane- )us.

The gas bomb for discharging the poison gas into the vault or otherenclosure is nounted in such position that the cap or )ther bomboperating device receives the impact of the firing pin 22. As shown inFig-- ires 1 and 3, the firing pin 22 is provided at ts lower end with apoint 42 for striking ;he cap or other operating device of the gas )ombto discharge the same. The gas bomb s indicated by dotted lines at 43 inFig. 1, LIld is provided with a cap or other firing device 44. Asupporting bracket 45 is provided For positioning the gas bomb 43beneath the iring pin 22. This bracket 45 consists of a vertical bar 46havin its lower end bent inwardly to provide a short flange 47 which ex-;ends below the bottom edge of the plate 14 aetween the horizontal lugs17. The upper and of the vertical plate 46 is provided with a. hole 48by which the upper end is hung )n a pin 49 projecting inwardly from theoracket plate 14. There is also provided at the upper end of saidsupporting bracket 45 i collar 50 which embraces and supports theflanged top of the bomb 43. This construc' tion provides a simple andeflective support for the removable bomb 43.

If desired, the bomb 43 may be protected by a casing 51 supported at itslower end on the lugs 17 and extending upwardly to the shelf 16, asshown in Fig. 2. The casing, however, will permit the escape of thenoxious fumes of the poison gas on the discharge of the bomb 43 and forthis purpose is provided with an opening 52. A pin 53, insertable in alateral hole 54 in the pin 49, may

be employed to prevent displacement of the bracket 45. This pin 53 iscurved so as to be easily manipulated. If desired, the pin 53 may bealso utilized for the purpose of locking the firing pin 22 againstmovement. In this case, the rod 18 is provided with a hole 55 located inone of its sides and in registry with the groove 26 in the firing pin22. By-

the form hereinbefore described being merely a preferred embodimentthereof.
